With this shape, the key is to split it into two figures which are simpler to figure out. Using the diagram, we can cut the figure along the side parallel to the 29 ft. Then we get one trapezoid whose area is 108 and a triangle whose area is 112.5. Adding them together we get 220.5 units squared.
Answer:
sin θ = 0.2426.
Step-by-step explanation:
The cot and cos are both negative in the second quadrant.
cot θ = 1 / tan θ = -4 so tan θ = -1/4.
θ = 165.96 degrees
sin θ = 0.2426.
The equation for volume of a sphere is (4/3)(pi)(r)^3. So you would plug in he radius 9 into the equation. It would simplify to equal (4/3)(pi)(729). It simplifies further to equal (972)(pi)
Using the slope-intercept form, the slope is −7 .
Answer:
The conclusion, since the null hypothesis was not rejected, is that the proportion of readers of the newsletter who own a Rolls Royce is significantly close to 0.6.
Step-by-step explanation:
A newsletter publisher believes that 60`% of their readers own a Rolls Royce.
This means that the null hypothesis is:
That is, that the proportion of their readers who own a Rolls Royce is of 0.6.
A testing firm believes this is inaccurate and performs a test to dispute the publisher's claim.
The alternate hypothesis is:
After performing a test at the 0.020.02 level of significance, the testing firm fails to reject the null hypothesis. What is the conclusion regarding the publisher's claim?
The conclusion, since the null hypothesis was not rejected, is that the proportion of readers of the newsletter who own a Rolls Royce is significantly close to 0.6.
